I really can't overstate exactly how bad it would be for the American internet to start requiring all users of all social media platforms to present ID. Lots of people have come up with lots of special, specific cases of why this would be bad, but few of them have seen exactly how broadly this will be catastrophic. I've yet to see anyone mention how this will exclude from the internet people who do not have ID to present - the same problem as in voter suppression - and that in some ways is one of the least of the problems.
Has it ever occurred to you to wonder HOW the United States government managed to find all of the Japanese people in California to round them up and put them in concentration camps? They used the census records. Having access to that database, it was pretty easy to figure out; after all, Japanese Americans tend to have Japanese last names, obvious on casual inspection of a list of citizens.
